ways.The Powder metallurgy process generally consis ts of three basic steps: powder blending die compaction, and sintering. Compaction is carried ou t at room temperature, and the elevated-temperature process of sintering is usually conduct ed at atmospheric pressure and under carefully controlled atmosphere composition.
T his constitutes a dilemma: From the view point of production efficiency, shorter sintering times would be preferable; but the correspondingly higher sintering temperatures are less economical because of higher maintenance costs for the sintering furnace. In iron powder metallurgy, common sintering conditions are: 15 - 60 min at 1120 - 1150 °C.
